In menuconfig, device drivers, Serial ATA and Parallel ATA drivers - the PATA drivers start with 'ACPI firmware driver for PATA' and continue to the end of that section. Use lspci, and google, and the help for the driver options, to determine which is appropriate for the chipset(s) on your motherboard. This is probably a case where keeping the original kernel and modules is a good idea, just in case adding drivers means the existing sda becomes something else (which will play havoc with /etc/fstab). I recommend adding an EXTRAVERSION for the new kernel, and giving the bzimage a unique name (or 'an unique name' for some of the people here). If the new drives appear, but cause your existing drive to 'move', revert to the original kernel and then I would mount by label or by uuid (man fstab). As always, backups are a good idea, but with luck it will be a walk in the park. ĸen -- After tragedy, and farce, "OMG poneys!" -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
